Beit known'that I, ALFRED A. HAWLEY, a citizen of the United States, residing at Ken nebunk, in the county of York and State of Maine, have invented certain new anduseful Improvements in' Steam Boxes and Tables Used'in Hardening Felt or Felted Articles; and I' do declare the [following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference markedthereon, which form apart of this specification.

Figure 1 represents the old form of the device; Fig. 2, a plan view of one formk of my improvement; Fig. 3, another form; Fig. 4,

a section on line w lw, Fig. 2; Fig. 5, a section v on liney y, Fig. 3; Fig. 6,a section on linex x, Fig. 2.

This invention relates to an improvement in the steam4 boxes and tables used in'hardening felt or 'felted articles; and it consists,essen tially,in`a steam-box having projeetionsupo This invention is herein illustrated as applied to the steam box or horn shown in United States Patent No. 203,147, and illustrated in Fig. 1 of the drawings; but the invention is applicable to any kindwk of a steam-box used in felting. It is simply shown in connection with this one for convenience of reference.

This box, as is well known, is constructed so thatthe fluffy battof felting material, when laidupon it, `is moistened by steam issuing from perforations in the top of the box, and in this mcistened condition the jigger7 is put down Aon the bat, and the Vlatter is pressed down and hardened for the ful1ing-box.

The steam-boxes, as at present constructed,

and as shown in saidFig 1, have asmooth top surface, a, on which the bat is to be placed and manipulatedby the jigger b.

The top of l from being moved away from the box by' thef jigger. Manifestly this planhas serious objections which my invention obviates-. The

bat is mashed down among the bers of the v cloth andhas to befrequently separated to keep them from being made homogeneous.

`It is very. diflicult, especially in hollow articles, to get the bat on the cloth and takes timey and trouble. .f

I dispense entirely with the cloth and place the-bat right on top ofthe box. l*

In the annexed drawings, thev letter A `indicates the'steam-box to which my invention sion of steam to the bat.'` Y e y In Fig. 2 is shown one formof my improve ment.

V is applied, and a are the holes for the emisl 'y t The top ofthe box is. madewith two ,f v

sets, 0D, ofgrooves crossing eachv other: and 'e forming the proj ections c.

In Fig. 3 is show n another form, there be ing only-one set of grooves, C, whichform ridges c. Ot`course there are a variety of ways in which the top of this box may be provided with projections without departing from the spirit of my invention.

upon my improved steamfbo'x and the jigger turned down and operated, the felt ispushedl down into the depressions inthe face of thel plate, and by frictionV is firmly held, so' thatV the jigger cannot force the batioft'of the box.,

What I claimis,' f, 1.` In the manufacture of felt, a' steam-box vhaving its top surface provided with projections,.as set forth. Y 2. In the manufacture of felt, a steam-box ridges c, asset forth.

In-testimonywhereof I affix my signature in presence of two Witnesses.
